Re: Hi everyone!
It's too late for summer 2008-09, which has already started, and probably too late for Winter 2009 (though there may yet be a chance). Currently, support positions are provided by Raytheon Polar Services Company, and food service jobs are subcontracted out to NANA. If you are really interested, start talking to the people who might hire you. RPSC is located in Centennial, Colorado (a suburb south of Denver), NANA is officially located in Alaska but most of the personnel are elsewhere.
If you are looking towards anything after Winter 2009 you should make your contacts with the people who have been to Antarctica over and over again, rather than with the company as such, as Raytheon is coming to the end of a 10 year contract, and the winner of the next 10 year contract has not yet been announced.
Expect it to take at least 3 months - and probably more - to physically qualify and get all the paperwork completed. In an emergency they can act more quickly, but they don't like to have to.
Antarctica is quite remote, and I've known men who got off the plane at McMurdo and decided they had to leave on the next plane out. It's not the place to be if you need to have people around you, and because everyone can be in close quarters it's also not the place to be if that will make you irritable. However, there is a reasonable degree of privacy if you want it - just expect to see the same people many times over every day.
If it still sounds good, go for it. Maybe I'll see you there.
